BACKGROUND OF THE INVENTION
Field of the Invention
[0002] This invention relates to golf clubs, and more particularly
to a golf putter configured to retrieve a golf ball from a cup on a
green, to assist a golfer with alignment prior to making a putting
stroke and to provide instant feedback on a putt made with the golf
putter.
State of the Art
[0003] There are approximately 29 million golfers in the United
States. Of those, sixty-one percent are over the age of fifty and
nearly twenty percent are over the age of seventy. In addition,
many golfers suffer from back injuries or have back issues that can
be aggravated by bending over to pick up a golf ball. This is
particularly true among senior golfers that make up the majority of
all golfers in this country. The present invention provides a
putter and putter head that not only allows a golfer to retrieve a
golf ball from a cup on a putting green or from any surface, but
also assists the golfer with alignment prior to a putting stroke
and provides instant feedback of the putting stroke of the
golfer.

DETAILED DESCRIPTION OF THE INVENTION
[0033] The present invention can be understood more readily by
reference to the following detailed description, examples,
drawings, and claims, and their previous and following description.
However, before the present devices, systems, and/or methods are
disclosed and described, it is to be understood that this invention
is not limited to the specific devices, systems, and/or methods
disclosed unless otherwise specified, as such can, of course, vary.
It is also to be understood that the terminology used herein is for
the purpose of describing particular aspects only and is not
intended to be limiting.
[0034] The following description of the invention is provided as an
enabling teaching of the invention in its best, currently known
embodiment. To this end, those skilled in the relevant art will
recognize and appreciate that many changes can be made to the
various aspects of the invention described herein, while still
obtaining the beneficial results of the present invention. It will
also be apparent that some of the desired benefits of the present
invention can be obtained by selecting some of the features of the
present invention without utilizing other features. Accordingly,
those who work in the art will recognize that many modifications
and adaptations to the present invention are possible and can even
be desirable in certain circumstances and are a part of the present
invention. Thus, the following description is provided as
illustrative of the principles of the present invention and not in
limitation thereof.
[0035] Unless specifically noted, it is intended that the words and
phrases in the specification and the claims be given their plain,
ordinary, and accustomed meaning to those of ordinary skill in the
applicable arts. It is noted that the inventor can be his own
lexicographer. The inventors expressly elect, as their own
lexicographers, to use only the plain and ordinary meaning of terms
in the specification and claims unless they clearly state otherwise
and then further, expressly set forth the "special" definition of
that term and explain how it differs from the plain and ordinary
meaning. Absent such clear statements of intent to apply a
"special" definition, it is the inventor's intent and desire that
the simple, plain and ordinary meaning to the terms be applied to
the interpretation of the specification and claims.
[0036] The inventors are also aware of the normal precepts of
English grammar. Thus, if a noun, term, or phrase is intended to be
further characterized, specified, or narrowed in some way, then
such noun, term, or phrase will expressly include additional
adjectives, descriptive terms, or other modifiers in accordance
with the normal precepts of English grammar. Absent the use of such
adjectives, descriptive terms, or modifiers, it is the intent that
such nouns, terms, or phrases be given their plain, and ordinary
English meaning to those skilled in the applicable arts as set
forth above.
[0037] Further, the inventors are fully informed of the standards
and application of the special provisions of 35 U.S.C. .sctn.112,
6. Thus, the use of the words "function," "means" or "step" in the
Detailed Description of the Invention or claims is not intended to
somehow indicate a desire to invoke the special provisions of 35
U.S.C. .sctn.112, 6, to define the invention. To the contrary, if
the provisions of 35 U.S.C. .sctn.112, 6 are sought to be invoked
to define the inventions, the claims will specifically and
expressly state the exact phrases "means for" or "step for" and the
specific function, without also reciting in such phrases any
structure, material or act in support of the function. Thus, even
when the claims recite a "means for . . . " or "step for . . . " if
the claims also recite any structure, material or acts in support
of that means or step, or that perform the recited function, then
it is the clear intention of the inventor not to invoke the
provisions of 35 U.S.C. .sctn.112, 6. Moreover, even if the
provisions of 35 U.S.C. .sctn.112, 6 are invoked to define the
claimed inventions, it is intended that the inventions not be
limited only to the specific structure, material or acts that are
described in the illustrated embodiments, but in addition, include
any and all structures, materials or acts that perform the claimed
function as described in alternative embodiments or forms of the
invention, or that are well known present or later-developed,
equivalent structures, material or acts for performing the claimed
function.
[0038] In the following description, and for the purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding of the various aspects of the
invention. It will be understood, however, by those skilled in the
relevant arts, that the present invention may be practiced without
these specific details. In other instances, known structures and
devices are shown or discussed more generally in order to avoid
obscuring the invention. It should be noted that there are many
different and alternative configurations, devices and technologies
to which the disclosed inventions may be applied. Thus, the full
scope of the inventions is not limited to the examples that are
described below.
[0039] As used throughout, the singular forms "a," "an" and "the"
include plural referents unless the context clearly dictates
otherwise. Ranges can be expressed herein as from "about" one
particular value, and/or to "about" another particular value. When
such a range is expressed, another aspect includes from the one
particular value and/or to the other particular value. Similarly,
when values are expressed as approximations, by use of the
antecedent "about," it will be understood that the particular value
forms another aspect. It will be further understood that the
endpoints of each of the ranges are significant both in relation to
the other endpoint, and independently of the other endpoint.
[0040] As used herein, the terms "optional" or "optionally" mean
that the subsequently described event or circumstance may or may
not occur, and that the description includes instances where said
event or circumstance occurs and instances where it does not.
[0041] The word "or" as used herein means any one member of a
particular list and also includes any combination of members of
that list.
[0042] As used herein, a "subject" is an individual. The term does
not denote a particular age or sex. A "golfer" is a subject that is
engaged in the act of golfing or an element thereof, such as
putting. As used herein, the term "subject" can be used
interchangeably with the term "golfer."
[0043] FIG. 1 is a perspective view of a golf putter 10 in
accordance with the principles of the present invention. The putter
10 is comprised of a putter head 12 coupled to a shaft 14. The
upper end of the shaft 14 includes a grip 16 that is attached to
the shaft 14. The head 12 includes a face 18 configured to contact
a golf ball when putting. The head also includes an aperture 20
configured to assist a golfer to pick-up or retrieve a golf ball
resting upon a surface or positioned inside a cup in a putting
green. In order to fit within a standard golf cup, the head 12 is
sized to fit within the cup, as will be described in more detail
herein. The shaft 14 is coupled to the putter head 12 proximate a
forward quadrant or heal portion of the head 12. Because the shaft
14 is not attached to the putter head 18 at precisely the center of
gravity of the putter head 12, the putter 10 would not be "face
balanced" if the shaft 14 were simply a straight shaft. "Face
balanced" is a term that applies to putters and means that when a
putter is balanced along its shaft between the grip and the head,
the face of the putter will position itself to be parallel to the
ground. Conversely, if the toe of the putter is pointing downward,
the clubface is not face balanced. In order for the putter head 12
to be face balanced, the shaft 14 is contoured to align with a
center of gravity of the putter proximate the face 18. That is, a
longitudinal axis A of the long straight portion of the shaft 14,
to which the grip 16 is attached at an upper end, extends
proximately through a center point P of the face, directly behind
which is located the center of gravity of the putter head 12. Thus,
the lower end of the shaft 14 includes bends 22 and 24 so that the
longitudinal axis A is properly aligned relative to the face 18.
The bend 22 may be an approximately 5 to 10 degree bend toward the
face 18 of the putter head 12. The bend 24 may be an approximately
10 to 20 degree bend toward the heel of the putter head 12. The
center of the bend 22 is about 1/2 to 1 inch above the top surface
of the putter head 12 and the center of the bend 24 is about 3 to 4
inches above the top surface of the putter head 12.
[0044] The total width of the putter head 12 from heal to tow at
its widest point is approximately 3.75 inches. A standard sized cup
for a putting green has an inside diameter of 4.25 inches. As such
the putter head 12 can fit within a standard sized cup. See FIGS. 2
and 7. The total width may be smaller or larger than about 3.75 so
long as the putter head can fit within a standard cup if the putter
head is to be used to retrieve a golf ball from the bottom of a
standard cup.
[0045] As shown in FIG. 2, the putter head 12 has a generally
cylindrical shape along the toe 30 and heel 32 portions.
Essentially, the putter head 12 is a cylinder with the face side
cut to form the putter face 18 and the back end cut to form the
trailing end 36 of the putter head 12. The diameter of the cylinder
of the putter head 12 is less than an inner diameter of a cup 38 so
that the putter head 12 can be inserted into the cup 38 to retrieve
a golf ball 40. A central aperture 20 defines a golf ball-grasping
portion 42 that forms a partial circle and has a diameter that is
slightly less than a diameter of a standard golf ball, which
according to the USGA must be no less than 1.68 inches. Because a
golf ball is formed from various polymers and other plastic
materials, by making the golf ball grasping portion 42 with a
diameter that is slightly less than 1.68 inches, such as between
about 1.67 and 1.6 inches, the golf ball 40 can be wedged within
the lower end of the aperture 20 by pressing the putter head 12
against the golf ball 40 when positioned within the golf ball
grasping portion 42 of the aperture 20. The trailing end 36 of the
putter includes two laterally spaced flanges 44 and 46 that extend
away from the face 18 and are separated by a trapezoidally shaped
opening 20' of the aperture 20. The flanges 44 and 46 allow for
positioning weight behind the putter face 18 on the toe side and
heel side of the putter face 18, with less weight positioned
directly behind the putter face 18 in order to help stabilize the
putter face 18 when putting, especially when the putter face 18
strikes a golf ball at an off center location.
[0046] As further shown in FIG. 3, the putter head 12 has a
generally C-shaped configuration and retains the golf ball 40 in
the central circular portion 42 of the aperture 20. The two flanges
44 and 46 are provided with crescent shaped weights 50 and 52,
respectively. The weights 50 and 52 are removable and replaceable
by removing threaded fasteners 56. The weights 50 and 52 can be
made from various materials in order to increase or decrease the
overall weight of the putter. For example, the weights 50 and 52
may be formed from aluminum, steel, brass, tungsten, plastic, or
any other material or allow in order to change the weight of the
putter head. In addition, if a golfer desires the putter to be more
toe or heel weighted, the golfer can replace one or both of the
weights 50 and 52 with heavier or lighter weights so that the
putter head is no longer face balanced. For example, golfers whose
putting stroke is generally straight back and straight through may
benefit more from a face balanced putter. Those golfers, however,
that have a more arc-shaped putting stroke may putt more accurately
with a putter that is more toe weighted to help the golfer rotate
the face of the putter through impact with the golf ball. The
putter head 12 of the present invention allows for customizable
weighting of the putter head 12 by the golfer to suit the golfer's
needs.
[0047] As further shown in FIG. 4, the weights 50 and 52 can be
removed by removing screws 56. The screws 56 are provided with a
star shaped aperture for use with golf-related torque wrenches
known in the art, such as those sold by TaylorMade and others golf
equipment manufacturers. The putter head 12 defines a pair of
recesses 60 and 62 that are sized and shaped to receive the weights
50 and 52, respectively. The depth of the recesses 60 and 62 are
also configures to substantially match a thickness of the weights
50 and 52, respectively, so that when attached to the head 12, the
bottom surfaces 50' and 52' of the weights 50 and 52 are
substantially flush with the sole 64 of the putter head 12.
Threaded apertures 56' are positioned within the recesses 60 and 62
for aligning with holes 56'' formed in the weights 50 and 52 and
are configured for receiving threaded fasteners 56 to retain the
weights 50 and 52 within the recesses 60 and 62, respectively. The
holes 56'' in the weights 50 and 52 are countersunk so that the
heads of the screws 56 are recessed within the weights 50 and 52
and do not protrude above the surfaces 50' and 52'.
[0048] As shown in FIG. 5, the putter head 12 may be fitted with a
plurality of weights 70-73, with each weight 70-73 taking up
approximately one half of a respective recess 60 and 62. In this
configuration, the golfer can further customize the distribution of
weight of the putter head 12 by placing heavier or lighter weights
toward the face 18 or trailing end 36 as preferred by the golfer
without affecting face balance of the putter, if desired.
[0049] Referring now to FIG. 6, the front face 102 of putter head
100 is provided with a plurality of concentric ridges 104 having a
center 106 that is centered between the toe side 108 and the heel
side 110 of the putter head 100. The height of the putter face is
between about 1 inch and 1.25 inches. As previously mentioned a
USGA conforming golf ball has a diameter of 1.68 inches. During a
putting stroke, the bottom edge of the face 102 of the putter 100
will be approximately 1/4 to about 1/2 inch above the putting
surface. In order to approximately center the center 106 with a
center of a golf ball resting on a putting surface, the center 106
is positioned approximately 1/4 to 1/2 inch, such as about 0.3
inch, above the sole 112 of the putter head 100 so that the center
106 of the concentric ridges 104 contacts the center of the golf
ball during a precise putting stroke. The ridges 104 may be formed
in the face 102 by milling, when the putter head is formed from
metal, such as aluminum, or by attaching a face insert to the face
102 that includes such ridges 104.
[0050] During a putting stroke, the energy imparted to a golf ball
affecting its speed is highest when the golf ball contacts the
center of the face 102 and long the center of gravity of the putter
face 102. Because the putter head 100 is bottom weighted as shown
in FIG. 3, the center of gravity of the putter head 100 is closer
to the bottom of the face 102 than the top. As such, the center 106
of the ridges 104 is positioned closer to the bottom of the face
102 than the top and helps to identify the sweet spot of the putter
face 102. Striking the golf ball on at this point imparts minimal
torque on the putter, thus transferring more predictable energy to
the ball, and if the putter face is square (i.e., perpendicular) to
the target line at impact and the path of the putter at impact is
in alignment with the target line, the initial direction of the
golf ball will be along the target line. The alignment channel 114
helps the golfer to visually align the putter head 100 and thus the
center 106 of the ridges 104 with the center of the golf ball prior
to a putting stroke. If the golfer does not exactly strike the golf
ball at the center 106 of the ridges 104, an off center torque is
applied to the putter head 100, which can slightly open or close
the putter head during the putting stroke. While the weights (see
FIG. 3) help to counter such torque from off center hits, the golf
ball may still be slightly deflected from the intended target line.
The concentric ridges 104 help to counter this by imparting counter
spin to the golf ball opposite to the affect of the torque
imbalance from an off center hit. Accordingly, the ridges 104 and
associated grooves help to direct the ball towards the intended
target line.
[0051] As shown in FIG. 7, when a golf ball 40 is resting at the
bottom of a cup 200, the head 12 of the putter 10 can be inserted
into the cup 38 to retrieve the golf ball 40 from the cup 38.
Pressing the putter head 12 against the ball 40 wedges the ball 40
into the aperture 20 of the head 12 as previously described.
Because the bottom of the cup where the ball 40 rests is centrally
located within the cup 38 so that the center of the ball is aligned
with the long axis L of the cup 38 the cylindrical portion of the
aperture 20 is also centrally aligned with the long axis L so that
when the putter head 12 is inserted into the cup 38, the aperture
20 will align with the ball 40 positioned at the bottom of the cup
38. Once the putter head 12 is inserted into the cup 38, even
though the putter head 12 may be positioned closer to one side of
the cup than the other, once the bottom of the aperture 20 engages
the ball 40, the putter head 12 and thus the aperture 20 will be
automatically aligned by the ball 40. Because the outermost edges
80 and 82 of the bottom surface of the putter head 12 are
positioned above the bottom surface 84 of the cup, the putter head
12 can be pressed against the golf ball 40 causing the golf ball to
become temporarily wedged within the aperture 20 so that it can be
retrieved from the cup 38 without requiring the golfer to remove
the golf ball 40 from the cup 38 by hand.
[0052] FIGS. 8 and 9 illustrate a golf ball 40 being struck the
putter 10 in accordance with the principles of the present
invention. As shown in FIG. 8, the face 18 of the putter head 12
has a loft of approximately 4 degrees relative to the putting
surface, but may be between about 2 degrees and 6 degrees. The
alignment channel 90 formed in the top of the leading edge of the
putter head 12 helps the golfer to align the center of the face 18
of the putter head 12 with the center of the golf ball. The shape
of the head 12 as shown in FIG. 8, has a stepped down shape from
the face 18 to the rear flanges 44 and 46 (see FIG. 9). The lower
position of the flanges 44 and 46 help to further lower the center
of gravity of the putter head 12 below the equator of the golf ball
40.
[0053] As previously mentioned, the putter head 12 is formed from
metal, such as aluminum and has a C-shaped configuration with a
front face and laterally extending flanges 44 and 46 separated by
the partial cylindrical aperture 20. The combination of the
material used to form the head 12 and its shape results in a tuning
fork configuration that causes a tone to be generated when the
putter head 12 strikes a golf ball 40. Moreover, the harder the
golf ball 40 is struck, the louder the tone becomes so that the
golfer obtains instant feedback on the amount of energy imparted to
the golf ball during the strike. This can be used to train the
golfer to better control distance of putting by trying to obtain a
particular loudness level of the tone for a put of a particular
distance. For example, a short putt of three feet will result in a
relatively quiet tone. The golfer can then repeat that putt until a
tone is achieved that matches the desired putting distance.
Similarly, for a longer putt of 15 feet, the golfer can practice
putting to achieve a particular tone loudness level that
corresponds to the proper putt distance with a golf ball is struck.
When putting a particular distance on a course, the golfer can then
putt to produce a particular tone level in order to produce a putt
of a desired distance and will receive immediate tonal feedback to
know whether the putt imparted proper energy to the ball.
[0054] The loudness of the tone is also affected by the quality of
the strike. That is, off center puts produce less tone volume than
center hits with the same club head velocity. Thus, the user can
also receive instant feedback on the quality of the putting stroke
as to whether the full tone amplitude is heard or if the tone has
been muted to some degree due to an off center strike. Thus in
addition to tactile feedback as to the quality of a putting stroke,
which is usually the only method a golfer has in determining
whether the golf ball was struck in the center of the club face,
the golfer will also receive audio feedback.
